“A gooey little sci-fi miracle.” Yes it is! Umbrella Entertainment has unveiled an official trailer for an indie horror comedy Mum, I’m Alien Pregnant, an amusing New Zealand creation about a young woman who gets pregnant… with an alien. This premiered at the 2026 Sundance Film Festival earlier this year playing in the Midnight section there. It’s the creation of the New Zealand filmmaking duo called “Thunderlips”, best known for their eccentric music videos & short films, serving up their first feature film. A messy millennial underachiever accidentally becomes alien-pregnant and must contend with skeptical doctors, a useless baby daddy, and her oversharing mother in order to survive & reclaim her life. Starring Hannah Lynch as Mary, Yvette Parsons as her mum Cynthia, Arlo Green as Boo, and Jackie van Beek as Ann. A tale of girl-meets-alien-boy and the body horror of pregnancy. Mary contends with her changing body; the unborn alien inside her; and her mum… finally reconciling all three in a slimy climax. I’ve seen this at Sundance (my full review) and it’s pretty good, especially wacky & weird, and very gross. An entirely original modern comedy.
Here’s the first official trailer for Thunderlips’ sci-fi comedy Mum, I’m Alien Pregnant, from YouTube:
Mary is a slacker living with her mother still trying to figure out what to do with her life in New Zealand suburbia. After an awkward sexual encounter with her strange new neighbour, she suddenly finds herself in the midst of an accelerated alien pregnancy! What follows is a classic Kiwi gross out take on pregnancy & parenthood that is not afraid to get weird, featuring standout performances from Hannah Lynch as the reluctant mother to be, Arlo Green as the hapless half-alien baby-daddy, and Yvette Parsons as Mary’s overbearing mother. Mum, I’m Alien Pregnant is written & directed by the New Zealand filmmaking duo known as Thunderlips – Sean Wallace & Jordan Mark Windsor, making their first feature film after many shorts and music videos previously. Based on their own 2024 short film Help, I’m Alien Pregnant. Produced by Ilai Amar, Morgan Leigh Stewart, Alix Whittaker. This first premiered at the 2026 Sundance Film Festival in the Midnight section earlier this year. Umbrella Ent debuts Thunderlips’ Mum, I’m Alien Pregnant film in NZ cinemas later in 2026. No US release date is set yet – stay tuned. Who wants to watch?
